ABSTRACT
Objective To study the clinical value of esophageal stent placement with radiation therapy for the middle-late pa-tients with esophageal cancer.Methods To perform esophageal stent placement and radiation therapy for the middle-late 35 pa-tients,and to perform radiation therapy for the middle-late 37 patients,then observe the clinical curative effects.Results The treat-ment group were significantly alleviated with dysphagia symptom after operation,which 32 cases sticked the entire radiation,ac-counting for 91.4%,no one can′t complete the treatment because of nutritional status reason.Survival time of one month after ra-diotherapy was up to 100.0%,and survival time of six months was 85.7% (30/35).But the contrast group with dysphagia symp-tom were aggravated or no relief,and needed parenteral nutrition.There were 23 cases to complete the entire radiation,accounting for 62.2%,and 5 cases happened esophageal tracheal fistula.Survival time of one month after radiotherapy was 83.8%(31/37),and survival time of six months was 62.2% (23/37).Two groups of cases in radiotherapy resistance difference was statistically signifi-cant,one month and six months of survival time were statistically significant (all P <0.05 ).Conclusion Esophageal stent place-ment with radiotherapy is more efficient than only radiation therapy to the middle-late patients with esophageal cancer.

ABSTRACT
Object To investigate the effects on the active components in Polygonum cuspidatum Sieb. et Zucc. and its different processed products. Methods The qualitative analysis of piceid and emodin are taken by TLC, and content of emodin was determined by TLCS and HPLC. Results The contents of emodin significantly increased in samples fried with rice wine, vinegar and salt compared with the crude. Conclusion Different methods and ajuvants made a certain influence on the contents of emotion in P. cuspidatum.
ABSTRACT
unprocessed sample. The statistics analysis showed that the emodin contents in raw Rhizoma Polygoni Cuspidati were significantly different from those in the different processed products of Rhizoma Polygoni Cudpidati. Conclusion: The processing temperature and time, wine, vinegar and salt could make the contents of emodin in Rhizoma Polygoni Cuspidati change in different degree.
